Abstract U radu je izrađen prototip uređaja prema komercijalno dostupnom AxiDraw uređaju koristeći aditivne tehnologije. Strojevi za proizvodnju aditivnim tehnologijama su sve pristupačniji i rasprostranjeniji, ne samo za profesionalne korisnike, nego i za privatne korisnike. Razvoj računalnih programa koji pomažu pri izradi 3D modela i kreiranju g-koda, uvelike pojednostavljuju dobivanje željene geometrije i spremanje iste u odgovarajući oblik kako bi korisnik, što je jednostavnije moguće, izradio željeni proizvod. Također, sama cijena materijala je sve niža, a novim materijali s boljim svojstvima se razvijaju svaki dan.
Zadatkom je trebalo opisati polimerne materijale i aditivne tehnologije, dimenzionirati i konstruirati dijelove prototipa, izraditi stroj primjenom aditivnih tehnologija, te pojasniti način puštanja izrađenog stroja u pogon.
Za izradu dijelova, korištena je FDM tehnologija 3D ispisa na uređaju za 3D ispis, Anet A8. Korišteni materijal pri 3D ispisu je ABS. Uz preporuku proizvođača materijala, a na posljetku i eksperimentalnim putem, odredilo se kako za korišteni materijal, najbolja temperatura mlaznice iznosi 220 °C, a temperatura radne podloge 95 °C. Uz temperature, postavljena brzina ispisa bila je 55 mm/s, a debljina ispisanog sloja 0,15 mm. Ova brzina i debljina ispisanog sloja dali su zadovoljavajuću kvalitetu ispisanih komponenti kao i prihvatljivo vrijeme ispisa svih potrebnih dijelova. Potrebno vrijeme ispisa svih dijelova iznosilo je 35 sati.
Osim dijelova proizvedenih aditivnim tehnologijama, komponente kao što su remenje, koračnih motora, servo motora, ležaja, vodilica i upravljačke jedinice koja se sastoji od Arduino UNO mikrokontrolera, Arduino CNC shielda i drivera koračnih motora su kupljeni zasebno. Pojašnjen je i postupak programiranja upravljačke jedinice.
Abstract (english) In this paper, a device prototype was created according to the commercially available AxiDraw using an additive technology machine. Machines for production using additive technologies are increasingly accessible and widespread, not only for professional users, but also for private users. The development of computer programs that help with the creation of 3D models and the creation of g-code significantly simplify acquiring the desired geometry and saving it in the appropriate format so that the user can create the desired product as simply as possible. Also, the price of the material itself is getting lower, and new materials with better properties are being developed every day.
The task was to describe polymer materials and additive technologies, dimension, and construct parts of the prototype machine, create a machine utilizing additive technologies, and clarify the way to put the machine into operation.
FDM 3D printing technology on a 3D printing device, Anet A8, is used to create the parts for the machine. The material used in 3D printing is ABS. With the recommendation from the material manufacturer, and experimentally, it is determined that for the material used, the best temperature setting of the nozzle is 220 °C, and the temperature of the working surface is 95 °C. Printing speed was 55 mm/s, and the thickness of the printed layer was 0,15 mm. This speed and thickness of the printed layer ensures satisfactory quality of the printed components as well as an acceptable printing time of all necessary parts. The required printing time of all parts was 35 hours.
In addition to manufactured additive technologies, components such as belts, stepper motors, servo motors, bearings, guides and the control units, consisting of an Arduino UNO microcontroller, an Arduino CNC shield and a stepper motor driver were purchased separately. The procedure for programming the control unit is also explained.
